Sandwich embroidery frame

ABSTRACT

An embroidering frame of the type adapted for supporting a portion of an embroidering canvas, so that the canvas threads are properly aligned longitudinally and laterally. The frame includes an upper template having studs extensible between the intersecting threads of the canvas, the studs then registering with apertures in a lower frame base, so as to align the canvas for embroidery work.

7 Claims, 5 Drawing Figures BACKGROUND OF THE INVENTION 1. Field of the Invention Embroidering. A great deal of attention has been given to various types of frames used in the support of embroidery canvases, weaving matrices, caning materials and the like. For the most part, these frames have included a bottom member and top member hinged with respect to each other and compressible together, so as to hold the canvas in place. Those frames used in embroidery work have been required to be of the same dimension as the canvas being worked. For example, a forty-inch frame would be required to work a fortyinch canvas. Thus, the embroideryframes could not be adjusted to fit over a minor segment of the canvas being worked. This shortcoming is emphasized, especially, in those types of embroidery stitches, such as the scotch and milanese stitches which tend to bias the canvas.

CACICI 1,411,908 GABLE, et al. 2,760,299 KEMLER 1,032,839 METCALFE 977,210 PENNYBACKER 356,012 SCI-IERPE 142,735 SCHIMANSKY, et al. 446,695

Pennybacker employs mating top and bottom frame members which support a chair seat. Similarly, Cacicis embroidery frame has folding side mating pieces which clamp the embroidery; however, Cacicis device cannot be moved over smaller potions of the embroidery. Gables paper stretching frame has two separate pieces secured to each other by means of connector 26 threaded bolt and wing nut 24. Schimansky employs separable frames which are secured to each other by means of bolts and Kemler employs two frames which are hinged at one end and utilize a clamping bead 19 and complementary groove 16 to support a photographic print. Scherpe and Metcalfe show various types of frames for stretching, respectively window screens and carpet screens.

SUMMARY OF THE INVENTION According to the present invention, the sandwich embroidery frame includes a base frame member defining an enclosed periphery for embroidering work, the frame having a plurality of vertically extending apertures. An upper template is configured complementally with respect to thebase frame and has a plurality of aligning studs supported in offset relationship beneath the template, so as to extend between the intersecting threads of the embroidery canvas and register with the frame apertures. Tightening means are provided for binding a canvas in place between the base frame and template. The frame is provided with rounded shoulders as a convenience in handling and concave recesses are provided in the bottom corners of the frame for housing the wing nuts, tie tacks or the like which may be used to compress or tighten together the template and frame.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the sandwich embroidery frame, shown supporting a segment of canvas for embroidering;

FIG. 2 is an exploded perspective, showing superposition of the template above the frame, prior to securement of an embroidery canvas therebetween;

FIG. 3 is a transverse section, taken through one side of the frame and template, showing the tightening bolts at the frame corners;

FIG. 4 is a perspective view of a modified frame and template of circular configuration, and

FIG. 5 is a transverse section of a rectangular frame modification wherein tie-tack type bolts are used for tightening the template with respect to the frame.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 and 2 a base frame 10 of rectangular configuration is illustrated as having secured on its flat top 48, a complementally configured template 12. Template 12 may include a plurality of studs 3 extending downwardly in offset relationship with respect to the template, so as to register with corresponding vertical apertures 32 in the base frame. Similarly threaded bolts 14, 16, 18 and 20 may extend through corresponding vertical apertures 22, 24, 26 and 28 in the corners of the base frame and the template and intervening canvas 36 may be secured to the frame by tightening identical wing nuts 34.

The lower corners of the base frame include arcuate cut-out segments 40 and 42 which define concavity 44 which houses either the wing nut 34 or the tie-tack close snap 34' illustrated in FIG. 5. The tie-tack bolts 18' and 20', for example, are secured to identical compressive clips 34' in the conventional manner. Manifestly, various types of threaded bolts and other securing or tightening means may be employed.

In the modification illustrated in FIG. 4 both the frame 10" and the template 12" are of circular configuration, the template being constructed with studs 30" and the entire assembly compressed by securing bolts 14", 16", 18" and 20".

conventionally, a needlepointer using a scroll type embroidery frame must choose a frame large enough to hold the entire width of her canvas. On the contrary, applicants sandwich frame covers that small portion of the canvas which is being worked and then may be moved onto a fresh or unworked area. The sandwich frame keeps the canvas threads both longitudinally and laterally aligned so there is perpendicular intersection of threads. This alignment inhibits or eliminates the biasing of the canvas caused by special stitches, such as the Scotch stitch and Milanese stitch.

In operation template 12 is inverted so that its studs extend upwardly, the portion of the canvas 36 being worked is registered onto the studs so that the studs extend through the canvas thread interstices, then the base frame 10 is secured onto the studs and the corners secured.

The frame and templates may be manufactured of wood, plastic or light metal, as desirable. In one modification the studs were placed along the frame at one inch to an inch and one half intervals. Manifestly, the types of materials used in the frames, the tightening means and the dimensions of frame and stud elements may be varied without departing from the spirit of invention.
